' brushes by the movement of said carriage. 4

This invention relates to a thread-dressing machine having a series of brushes for laying the projecting fibers of the thread, an ironer for polishing the thread, and a series of twisting-head devices for putting the proper twist upon the thread as it passes vertically in front of said brushes and said ironer; and the object of my invention is to provide a power-driven carriage having a series of thread-tension rods mountedthereon and said carriage arranged to impart a reciprocating motion to that portion of the thread between the twisting-heads and the ironer, whereby the thread is caused to roll upon the peripheral surfaces of the brushes prior to its being polished by the ironer.

The invention consists of the novel construction and combination of parts, as hereinafter described and claimed.

In the accompanying two sheets of drawings, Figure 1 represents a partial front-elevation of a thread-dressing machine having an ironer,brushes, and thread-twisting heads rotatably mounted on the machine-frame,'respectively, and also illustrating a movable carriage having a series .of thread-tension rods provided with thread-eyes for directing the thread from the twisting-heads and also indicating the traversing movement the thread takes over the peripheral portions of the Fig. 2 is a vertical cross-sectional view taken in line X X of Fig. 1. Fig. 3 is a top-plan sectional view takenin line Y Y of Fig. 1,

showing the arrangement of parts embodying my improvement as when the carriage is at one end of its travel on the machine-frame. Fig. 4: is a top plan view of thedriving ar rangement for the carriage, showing the position the parts assume when the carriage is at the opposite end of its travel on the machine-frame. Fig.5 is a detail view of one .ner shown in Fig. 5.

' of the antifriction-rollers for the movable carriage.

Like characters of reference indicate like parts in the several views of the drawings. Three cylindrical brushes A A A are rigidly secured upon shafts b b hthat pass through the-'journal-bearings of brackets c c 0, which are bolted to the end frames (Z d of the machine. On one end of each brush-shaft b is made fast a pulleyv e, which is driven by a belt connection with a pulley on the drivingshaft of the .machine. Above the brushes, which extend in parallel alinement with each other, is a tubular ironer B, having reduced end portions ff, that pass through the journal-bearings of brackets 0 c, which are bolted to the end frames d d of the machine. A pipe g passes through the ironer B, and said pipe is arranged to receive steam for heating the same. On. one end of the ironer B is made fast a pulley e, which is driven by a belt connection with a pulley on the driving-shaft of the machine. Below the brushes is arranged a series of thread-twisting heads 72, 71, which are mounted on the beam d, forming a part of the machine-frame, and each of said twisting-heads is driven by a band or cord connection a with the whirl-shaft of the machine.

The construction of each of these twistingheads IL is the same as that shown in United States Letters Patent No. 756,487, issued to me April 5,1904. The axial centers of each and all. of the twisting-heads are approximately in vertical alinement with the peripheral surfaces of the brushes and ironer.

. A movable carriage is mounted on the ma- 7 rotatably mounted on stud-bolts m m, secured in each end frame of the machine in the man- Each of the bars of the carriage has a series of thread-tension rods an adjustably mounted thereon, and each of said rods is provided with a thread-eye a. Said rods n n are held in position upon the bars jy'j by set-screws 0 0. Y

A support 11 is secured upon the side of one of the end frames (Z of the machine by bolts 92 p, and said support is recessed on its upper side to receive a sliding plate 9, which is bifurcated at one end to receive the end of a rod 9", whose opposite end is secured to an eccentric t. The plate (1 is held in place on the support p by screws 8, which pass through gibs t t,that overlap the upper surface of said plate.

Each of the bars 7' of the carriage project outwardly from one end frame (Z of the machine, and said carriage has this projecting portion of its bars connected together by a rod 14, which passes through a slotted opening formed in the support 1) and plate q, re-

spectively. The slot formed in the support 19 extends longitudinally of the carriage, as at while that of the slot formed in the plate (1 extends in an angular direction from the carriage, as at 10 The eccentric t is made fast upon the hub of a pulley e, which is loosely mounted upon a stud-shaft 01, secured in the side of the machine-frame. Said pulley e is driven by a belt connection e from a pulley w, made fast upon the driving-shaft m of the machine.

The brushes and ironer revolve with the directed movement of the thread.

The thread (designated by letter y) to be rolled and polished by my said machine comes up from a sizing-box (not shown) and passes through a twisting-head h, which puts the proper twist upon the thread. Thence the thread passes in contact upon the peripheral surface of the lowermost brush A, thence in the eye of a tension-rod n to be directed to contact upon the peripheral surface of the next upper brush A, thence in the eye of another tension-rod n to be directed to contact upon the peripheral surface of the uppermost brush A, thence in the eye of the uppermost tension-rod 77/ to be directed upon the peripheral surface of the ironer B, and from said ironer the thread passes to be wound on the spools next above on the machine. The brushes lay all the projecting fibers of the thread, and as the thread moves in the manner above described the driving-shaft a; transmits a sliding movement to the plate g by means of the eccentric t, and with each alternate movement of the plate q, as shown in Figs. 3 and 4:, said plate imparts by its slot arrangement a reciprocating motion to the carriage, whereby the thread is caused to take a longitudinal rolling movement upon the peripheral surfaces of the brushes, first to the full-line position, (shown at y in Fig. 1,) thence to the broken line position, (shown at g in said figure.) In this manner the thread is rolled round and smooth prior to its receiving the finishing polish by the ironer.

By giving a reciprocating movement to the hread in the manner described the surfaces th e brushes are kept from being worn unnly as otherwise would not be the case if the thread moves direct from the twisting-head to the ironer.

Having described my improvement, what 1 claim, and desire to secure by Letters Patent, is

1. In a thread-dressing machine having an ironer, a series of brushes and a series of thread-twisting heads rotatably mounted on the machine-frame and driven by power therein, the combination therewith, of a carriage properly mounted on the machine-frame and comprising a series of bars extending longitudinally of the ironer and brushes; a series of thread-tension rods ad justably mounted on each of the bars of said carriage and said rods provided with thread-eyes for directing the threads from the twisting-heads to the ironer; and means mounted on the machine-frame for giving a reciprocating movement to said carriage, whereby the threads are caused to take an alternate rolling movement upon the peripheral surfaces of the brushes, substantially as set forth.

2. In a thread-dressing machine having an ironer, a series of cylindrical brushes and a series of thread-twisting heads rotatabl y mounted on the machine-frame and driven by power therein, the combination therewith, of a carriage movably mounted on the machine-frame and said carriage havinga rod at one end thereof; two or more series of thread-tension rods adjustably mounted on said carriage and said rods provided with thread-eyes for directing the threads from the twisting-heads to the ironer; a support secured upon the machineframe and provided with a slotted opening extending longitudinally of said carriage, and arranged to receive the rod of the same; a plate slidably mounted in said support and provided with an angular slotted opening to receive the rod of said carriage; a drivingshaft; a pulley made fast on said shaft; a studshaft fixed to the machine-frame; a second pulley loosely mounted on said stud-shaft; a belt connection from the first mentioned pulley to the second-mentioned pulley; an cecentric made fast upon the hub of secondmentioned pulley and having a rod connection to said plate, so arranged that a sliding movement of said plate imparts, by its slot, a reciprocating movement to said carriage, whereby the threads are rolled upon the peripheral surfaces of the brushes, substantially as set forth.

3. In a thread-dressing machine, the combination with the frame of said machine, of a tubular ironer mounted in proper supports of the machine-frame and driven by power therein; a steam-pipe passing through said ironer; a series of horizontal cylindrical brushes rotatably mounted on the machine-frame; a se ries of thread-twisting heads rotatably mounted on the machine-frame and having their axial centers in vertical alinement with the peripheral surfaces of said ironer and said brushes; stud-bolts secured in the machine frame; a roller loosely mounted on each of said bolts; acarriage provided with a series of slotted openings extending parallel With each other and arranged to receive said rollers;
